Short hair (L) is dominant over long hair (1) in rabbits. Two heterozygous rabbits are mated. Show the punnett square. What phenotypes are expected, and in what ratios of the bunnies produced? Parents Genotypes:

When two heterozygous short haired rabbits are crossed, the short hair being dominant and the long hair recessive, the phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1.

Explanation:

The crossing of two hybrid individuals for a trait has the probability of producing offspring that exhibit the dominant trait at 75% and the recessive trait at 25%, with the ratio of the dominant trait to the recessive trait being 3:1.

Considering the hair length trait, in rabbits the short hair (L) is the dominant trait and the long hair (L) is recessive, two heterozygous hybrid individuals Ll are crossed:

Genotype of the parents:

Ll X Ll

Punnett Square

Alleles        L      l

L                 LL    Ll

l                  Ll      ll

Where the offspring have a genotype:

Ll 50%

LL 25%

ll 25%

With a ratio Ll:LL:ll of 3:1:1.

Phenotype:

Short hair 75%.

Long hair 25%.

Phenotypic ratio short hair: 3:1 long hair.

In the crossing of two heterozygous short-haired rabbits, taking into account the dominance of the short hair,  phenotypes in the offspring will be 75% short hair and 25% long hair, with a short hair:long hair ratio of 3:1

answer by yourhope:

answer is

human impact on the environment can be seen in the deterioration of the !

: )

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
